One of the most powerful ways of increasing user engagement on your blog or website is by using interactive quizzes. People love to learn about themselves (personality quizzes) or to put their intellect to the test (trivia quizzes). Your users might even like to share the quizzes with their friends to challenge them, thereby bringing in more traffic to your website.
If you own a WordPress website, the WP Quiz Pro plugin can help you integrate beautiful and engaging quizzes without you having to break a sweat. It comes with a powerful quiz building interface coupled with a lot of customization options to help you create awesome quizzes which look great, and are extremely engaging to play.
